Sam, whose mass is 71 kg , straps on his skis and starts down a 40 m -high, 20∘ frictionless slope. A strong headwind exerts a horizontal force of 200 N on him as he skies. Use work and energy to find Sam's speed at the bottom.

A skier with mass 64.0 kg starts at rest at the top of an 842 m long ski slope, which makes an angle 13.0 ∘ with the horizontal. A typical coefficient of friction between skis and snow is 5.20×10−2. skiers don't go straight down the hill- they zigzag back and forth. Even though they still end up at the bottom of the hill, they've lost more energy to friction because friction is a non-conservative force. Let's say due to zigzagging,...

Sam, whose mass is 71 kg , straps on his skis and starts down a 58 m -high, 20 degree frictionless slope. A strong headwind exerts a horizontal force of 200 N on him as he skies. Use work and energy to find Sam's speed at the bottom. Express your answer to two significant figures and include the appropriate units.

Question 2 A 50 kg skateboarder is planning a trick for an upcoming competition. She starts out riding her 7 kg skateboard with initial speed of 2.5 m/s. She and the skateboard then slide down a slope of height 3 meters. At the bottom of the slope, she steps from the first skateboard onto a second stationary 7 kg. skateboard, leaving the first skateboard moving at half the speed it was before the switch. Finally, riding...
